Well the situations are all variable and not one setup can transfer to another perfectly every time . Your contrasting two different types of light . 110wtts total of Pl-l lights Vs. 150wtts HPS . The obvious winner in my book without having grown using the Pl-l Lights as of yet would be the HPS setup because you have 40 watts more of HPS .150w of HPS would be more intense of light than the 110w PL-L . EDIT: I just thought about it and i can re-call someone harping on 150w HPS because of the inefficiencies of the 150w sytems. Sooo someone please correct me if im totally off on this point .

Also your going to have to consider what ventilation system you will be capable of because the HPS light is going to run hotter . The Pl-l light on the other hand will remain relatively cool and wont need you to extract the hot air you would with the HPS.

Additionally your wanting to grow 4 plants under a 150wtt HPS ?? Or even yet 4 plants using a double 55Wtt system is both inefficient and simply not enough . I've heard that as a rough estimate when it comes to CFL ( which Pl-l are HO and more effiecient than cfls ) the best thing to do is use a minimum of 100Wtt for your first plant and 50-75wtts more each each plant after . So if you plug the numbers in (100w + 3(75w) = roughly 325wtts for healthy dank buds .

When it comes down to it just weigh your options and see which one you want to deal with . My choice personally is to go with the Pl-L Lights but thats just my prefrence .

I've read similar statements elsewhere, but with no facts to back it up, so i'm curious if you're basing your comments on someone's opinion or something more concrete. Thanx

I dont recall the forum that i found that information on because it was linked into some other forums so truthfully that is he said she said hearsay . Wish I had the link...

That gives me No help what so ever. I know alot about 2g11 bulbs and PL_L I am asking you what is a better to grow with 250 watts of PL-l or 250 watts of hps. which will yeild higher would you say???

You have my information incorrect thats why I think you got the wrong idea. haahha. I know its about prefrence but I never grew with either so I would not know what to chose. So thats why I am asking the forum. For the advice before I go out and spend the dough

I could of just posted "PL lamps are the best stealth lamps. Go get one!", but like many things in life, more effort = greater rewards. The length of the post serves as a filter, removing the undedicated!

With most lamps, as you increase Wattage, you also increase heat. With HID lighting, a lot of the energy used, is given off as heat, and as weird as this sounds, a lot of growers actually equate the intense heat of an HID as being a good thing, the more intense the better! Obviously this is erroneous.

The hotter the lamp, the farther away you need to position your plants. To get maximum efficiency from a 250W HID lamp, you would need to position it 5" from your plants. At that distance, your plants will burn. Growing indoors, heat is always the enemy.

A PL lamp, on the other hand, enables maximum efficiency almost right up to touching its surface! Ergo, you get to use more of the available Watts for your plants, as light.

But an HID lamp can throw usable light farther.

So, which is the most efficient when it comes to yield is a simple question: What is your growing style?

If you are scrogging, or SOGing, all the bud falls within around 1 foot (height), and because all the important (bud) parts of your smaller plants fall within this optimum light zone, the PL lamp will yield more bud.

If you grow tall plants, a good HID lamp of the same Wattage will yield more bud.
